Type of respiration which involves step by step breakdown of carbon chain molecules in the cell is called:
Correct answer: C. Cellular respiration
- A. External respiration
- B. Pulmonary respiration
- C. Cellular respiration
- D. Cutaneous respiration
Explanation
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), which is used to power various cellular activities. ATP is often referred to as the "energy currency" of the cell. Cellular respiration occurs in three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (including the electron transport chain and chemiosmosis).

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
